How the 32206-DF model number is decoded
Load sharing in 32206-DF depends on spacer face parallelism; a cocked spacer concentrates the reversing thrust on one bearing of the pair and shows up as asymmetric raceway wear at overhaul. Clamp the assembled pair axially through the cones — never through the rollers — and verify the 42.5 mm overall width against the catalogue value before final torquing of the shaft nut.The SKF 32206/DF is a 30×62×42.5 mm matched tapered-roller set — two single-row bearings in face-to-face (X) matched pair arrangement, ground and shipped together with the axial clearance fixed at the factory.The code breaks down as base bearing 32206 plus matched-set suffix /DF: two bearings of the 30 mm bore size, paired face-to-face (X) matched pair, with the 42.5 mm overall width spanning the whole arrangement. Face-to-face matching puts the small rib ends outward, so the pressure cones cross inside the pair; 32206-DF therefore runs cooler where the shaft expands axially, at the price of lower moment stiffness than an O-arrangement of the same 30 mm bore. With a pair mass of 590 g across the 30×62×42.5 mm envelope, the set replaces what would otherwise be two separate bearings plus spacer grinding work — the factory setting is the engineering value being purchased. Dimensional interchange map: within its boundary plan the 30×62×42.5 mm envelope of 32206-DF is fixed, so shoulder, spacer and seal drawings can be dimensioned straight from the catalogue table.
Typical equipment & failure modes
Common applications
- differential and pinion drives
- pump and compressor shafts
- machine-tool spindles
- belt-driven fan and blower shafts
Known failure patterns
- thermal preload runaway in an O-arrangement pair when inner-ring heat expands the setting
- roller large-end smearing against the cone rib after EP lubricant film failure
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- fretting corrosion on a loose rotating shaft seat
- rib-roller contact scoring from loss of the EP additive film
Selection pitfalls — read before you substitute
- Clamp the 32206-DF pair axially through the cones, never through the rollers; pressing force across the roller complement brinells the raceways of both bearings at once.
- Setting is built into 32206-DF; the classic field error is re-adjusting a matched pair as if it were two loose single bearings, which destroys the /DF clearance class.
- Clamp the 32206-DF pair axially through the cones, never through the rollers; pressing force across the roller complement brinells the raceways of both bearings at once.
- The 106/116 kN ratings are SKF catalogue 17000 values for this execution; SKF can revise internal geometry without changing the order number, so keep the catalogue version (PUB BU/P1 17000/1 EN, 2018) with the specification.
- Quote the full SKF 32206/DF designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of 32206-DF?
The SKF 32206/DF is a matched pair of single-row tapered roller bearings in face-to-face (X) matched pair arrangement with 30 mm bore, 62 mm outer diameter and 42.5 mm overall width (1.181 × 2.441 × 1.673 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 106 kN, C0 116 kN, fatigue load limit Pu 12.7 kN, reference speed 7,500 r/min, limiting speed 11,000 r/min, mass about 0.59 kg.
What does the /DF suffix on 32206-DF mean?
The base 32206 is the ISO 355 single-row bearing; the /DF suffix marks the matched-set execution — the arrangement (face-to-face (X)), the ground spacer and the factory-set axial clearance class. A matched set cannot be assembled from loose single bearings; quote the full designation when ordering.
Are the C and C0 ratings of 32206-DF for one bearing or the pair?
They are for the complete matched pair: C 106 kN dynamic and C0 116 kN static already include load sharing between the two bearings. Do not halve them for single-bearing checks, and do not compare them directly with the single-row 32206 table values.
Can 32206-DF be adjusted like two loose tapered bearings?
No — the axial clearance is set at the factory by selective spacer grinding. Mounting work is limited to clean seats, correct fits (k5 on a rotating 30 mm shaft) and axial clamping through the cones; re-setting in the field destroys the matched clearance class.
When should a face-to-face (X) matched set be chosen?
Choose the face-to-face (X) set where the shaft grows thermally or alignment is imperfect — the converging load lines tolerate deflection. It is the default choice for wheel hubs and general gearbox shafts at the 30 mm bore.
